“…The spin states split due to the opposite phase shifts for spin-up and spin-down neutrons. As long as the angular splitting measured in a differential phase contrast setup is moderate, a dark-field contrast-like signal [133] provides images of magnetic field distributions, as reported in 1994 in the course of presenting radiographs recorded in a doublecrystal setup [134]. Recently, similar results achieved with the now available shearing interferometer technique have been reported [135].…”

Neutron imaging can provide two- or three-dimensional, spatially resolved images of the internal structure of bulk samples that are not accessible by other techniques, making it a unique tool with many potential applications. The method is now well established and is available at neutron sources worldwide. This review will give a survey of the technique of neutron imaging with a special focus on neutron tomography; the basics of the method as well as the technology of instrumentation will be outlined, and the techniques will be illustrated by representative applications. While the first part of the paper focuses on conventional attenuation contrast imaging, the second part reviews and critically assesses recent methodical developments.

“…These properties make neutrons ideal for applications in a wide range of scientific and industrial applications. [1,2,4,[18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33] Most neutron imaging facilities use either cold or thermal neutrons (%2-25 meV) since at these energies neutrons have relatively large effective interaction cross sections with matter, but are still able to penetrate bulk matter (c.f. energies of 10-100 keV used for similar experiments with X-rays).…”

Many materials used for energy conversion have a complex structure and chemical composition, knowledge of which is important for both understanding the function of materials and energy conversion systems and for their further development. Synchrotron radiation and neutrons can make an important contribution to understanding the function of such systems. Taking examples from the fields of fuel cells, gas separation membranes, batteries, solar cells, and catalysts, the use of radiography, tomography, diffraction, scattering, and absorption edge spectroscopy is demonstrated. The strength of such methods is the in situ characterization of processes and compositions, and so the focus is on these aspects.

“…Developments concerning new experimental methods such as phase-contrast, energy-selective, dark-field and polarised neutron imaging have witnessed substantial progress in NT [ 3,4,5,6,7,8,9,10,11,12,13 ]. In addition, the utilisation of innovative detector systems enabled to overcome some of the limits of conventional neutron tomography concerning spatial and time resolution [ 14,15 ].…”

A cone beam arrangement was applied to cold neutron imaging by using an elliptic focusing guide. The beam parameters were characterised in the focal point and at the sample position. Improved experimental conditions for tomographic applications were achieved by using the advantage of a point source geometry providing a larger beam and enabling geometric magnification. The experimental data were compared with Monte Carlo simulations. The performed experiments and simulations prove superior spectral and geometrical homogeneity of the cone-beam setup realised, as compared to the classical pinhole geometry.
